Peavey SP® 4
The SP 4 is a quasi‑three‑way, full‑range, bi‑ampable sound‑reinforcement system. It features two premium 15″ Black Widow® woofers with 4″ voice coils, an RX 22CT compression driver and utilizes Peavey’s exclusive “Quadratic Throat Waveguide™” asymmetrical horn design. The horn is engineered to aim coverage 15° upward and 35° downward to better focus the sound toward the audience rather than over their heads.
